# Introduction to Debusine

## What is Debusine

At its core, Debusine manages scheduling and distribution of Debian-related tasks to distributed worker machines. Those tasks are usually tied together in various workflows.

Workflows can have many different purposes, but Debusine’s primary workflow is one built around a package update: it takes a new source package, builds binary packages, launches a battery of QA checks, signs the packages, makes them available in an APT repository (or uploads them to an external repository).

Debusine is being developed by Freexian to help support the work of Debian developers, by giving them access to a range of pre-configured tools and workflows running on remote hardware.

We want to make it as easy as possible for Debian contributors to use all the QA tools that Debian provides. We want to build the next generation of Debian’s build infrastructure, one that will continue to reliably do what it already does, but that will also enable distribution-wide experiments, custom package repositories and custom workflows with advanced package reviews.

## Debusine for Debian development

With debusine.debian.net Debian developers have access to workflows to prepare the updates that they want to upload to Debian. Each of their updates will be built on multiple architectures (with sbuild) and the resulting binaries will go through various QA tools that have been hooked into Debusine (including autopkgtest for the package itself and for its reverse dependencies, lintian and piuparts).

## Next generation Debian infrastructure

Debusine has been developed to fulfill the same requirements as the corresponding infrastructure in use in Debian, making it viable as a future replacement for wanna-build and buildd, and possibly more.

The end goal is to provide a more integrated experience to Debian developers while enabling many new features that are entirely out of reach with the current infrastructure.

Debusine will support creating pipelines with build, QA, approval and signature steps that are triggered by package uploads. Pipelines will understand the distinction between official Debian workers and external workers, and only schedule builds targeting official distribution on official workers.

## Run distribution-wide QA experiments

By providing a standard orchestration layer and low-level package build and QA tasks, Debusine makes it much easier to do large-scale distribution-wide tasks. One can build workflows for test rebuilds or transition preparation, without needing to recreate the common infrastructure for scheduling and executing tasks.

The distributed design of Debusine and its native cloud integration means that any Debian developer can schedule archive-wide QA experiments without disturbing the day-to-day work.

Debian-friendly people and companies will be able to sponsor external computing time, while trusted builds will remain under Debian’s control.
